I've had my 3-4" ocellaris for about a decade now (from when he was only about 1")... He's travelled with me between cities on one coast and then across the country when I changed coasts, as the only member of my tank I've kept during moves.
For the past few years he has been incredibly aggressive toward new tank inhabitants, leading toward him being the only fish in the tank for large periods of time. I've tried many varities of tankmates. The only one that seemed to last a long time, attacked only rarely, was a longnose hawkfish.
Recently I introduced 3 small blue chromis and a yellow tang of similar size to the clown into the tank. I've seen the clownfish chase after the chromis a bit, which I expected, but of bigger concern to me is that I've started to notice a little notch forming in the tail of the tang. I haven't actually seen the clown attacking the tang, but I'm relatively that must be the cause. (I'm open to other ideas? It doesn't look like disease so far, and I don't see any other signs of disease on the tang.)
I've tried rearranging the furniture, so to speak, in the past when introducing new fish, and it has never seemed to make much of a difference.
Does anyone have any ideas for squelching this aggressive behavior?
The tank is a 24" cube, so approxitely 60 gallons I suppose.
Inhabitants:
- ~3-4" clown
- ~3" yellow tang
- 3 ~1-1.5" blue chromis
- cleaner shrimp
- large long spine urchin
- RBTA (also introduced very recently-- no hosting yet. The clown has been with both an LTA and a BTA in the past.)
- GSP
Thank you!
